Hi all, I have been having problems with Aperture 3. When attempting to upgrade my managed files library from Aperture 2 > Ap 3, the process continually runs out of disk space, freezes and you have no option but to restart Aperture. It appears that the software has been built as such that it needs the same amount of space on the hard drive it's installed on, as the size of the library it's trying to convert. For example, I have a 96Gb managed masters library stored on an external HD. Aperture 3 is installed on my MBP internal HD. When attempting to convert the files Aperture wants to use 96Gb on the internal HD. Now the drive is only 120Gb to start with, then there is all the stuff on there for other programs as well. Plus documents etc. As the internal HD does not have 96Gb free, I am unable to upgrade the library. I am, it appears stuck with this issue with no way of updating the library until Apple release a fix of some kind. I am not alone in this issue either. The discussions.apple.com site has many reports of the same from other people. I just wanted to let you all know, before someone else runs into a similar issue. I would recommend that you stick with Aperture 2 until a workaround or fix is found. I hope this helps someone.
